High-throughput imaging is highly desirable in intelligent analysis of computer vision tasks. In conventional design, throughput is limited by the separation between physical image capture and digital post processing. Computational imaging increases throughput by mixing analog and digital processing through ...

This paper discusses the design of a highspeed parallel sampling system, which is used for the acquisition and digital processing of video frequency signals in portable image applications. The system is mainly composed of TMS320VC5410 (DSP) and TLC5510 (A/D converter). Its high-speed parallel ...
Key to our approach is a completely new conceptual approach of spectrally decoded electro-optic sampling, which has its roots in the theory of the photonic time-stretch analog-to-digital converter19,20 where a similar problem called dispersion penalty was identified and solved 21. As we will ...
